1 UNITED STATES PATENT OFFlCE VICTOR NOAK HYBINETTE, 01' JACKSON, MICHIGAN, ASSIGNOR TO HYBINETTE PAT- ENTS CORPORATION, 01 JACKSON, MICHIGAN.

ANTII'ATIGUE ALLOY.

' No Drawing.

My invention relates generally to metal all s and more particularly to an aluminum a 0 such as is disclosed'in my co-pendin provide an aluminum allo that is character-' ized by having the desirab e qualities of being anti or non-fatiguing and which result-is attained b minimizing the proportions of certain of t e metals enterin into the alloy.

In my above mentioned co-pending patent application, and in the patent application and issued patent of Victor Evers Hybinette,

above mentioned, the alloy consists of aluminum, nickel and/or cobalt, metals of the chromium group such as chromium, tungsten, molybdenum and/or copper and/or manganeze and/or magnesium and for silicon,'and

I propose to produce my anti-fatigue alloy in much the same manner as the aluminum alloys setforth in said applications and issued patent are produced, but in order to impart to the alloy the desired non-fatiguing quality, I lessen the quantities of copper, magnesium and silicon that enter into the alloy. I have found that in tests and experiments,

Application filed July 11, 1927. Serial No. 205,026.

the alloys set forth in the above mentioned patent applications have exceptional advantages, due to their anti-fatigue qualities and such desirable quality is enhanced by decreasing the copper, silicon and magnesium contents. I believe that this result is only what might be expected, for it is evident that the alloys containing relatively large amounts of segregations do not have the non-fatiguing qualities to the same extent as alloys that are more on the order of solid solutions.

"My improved anti-fati e alloy consists mainly of aluminum, nic el and metals of the chromium group, with manganese and/or other heavy metals containing about 0.20O.50% each of copper, magnesium and silicon. In the production of my im-' proved alloy, the-same is quenched at about 900 F. and aged at from 200 to 4:00 F.

I claim as my invention:

l. A low fatigue alloy comprising at least 95% aluminum, nickel less than 2%, metals of the chromium group less than 1%, and less than 0.50% of copper.

2. A low fatigue alloy comprising at least 95% aluminum, nickel less than 2%, metals of the chromium group less than 1%, and less than 0.50% each of copper, magnesium and silicon, said alloy being quenched at about 900 F. and aged between 200 F. and 400 F.

In testimon whereof I alfix my signature.
